Again,
another parts development directly from Evolution Racewerks' 135i Time Attack racing
program. The factory diverter valves were causing an issue of not being
able to hold up against the rigors of high boost application, therefore
they needed to be replaced. Thus attention was brought to the factory
charge pipe that houses the diverter valves and the need to optimize
for maximum performance on a race car facilitated the need
for a new pipe to be built. Often ignored, charged intake airflow
characteristics greatly affect throttle response, turbo lag and
ultimately maximum power potential.
Smooth bends and minimal obstructions
are ideal. This is not the case with the factory charge pipe.
The factory charge pipe features a sound baffle for the
diverter valves. This sound baffle is connected on the side of the
factory charge pipe which splits airflow. This causes
turbulence inside the pipe which slows the charge intake air velocity
(speed of the air traveling inside the pipe). By removing this
turbulence (by eliminating the factory diverter valve sound baffle), increased throttle response, decrease turbo lag and ultimately higher
maximum power potential can be realized. Evolution
Racewerks' Charge
Pipe Upgrade eliminates this sound baffle and thus eliminating the unnecessary turbulence in the charge
pipe, keeping charge intake air velocity at it's maximum. 3" 6061
Aluminum piping was used to properly match the size of the throttle body
as well.

Since one of
the reasons for changing out the factory diverter valves was to prevent
boost leaks (from prematurely opening on high boost), causing boost
leaks while upgrading the diverter valve would be counterproductive.
The connection at the throttle body was looked over very carefully. The
factory diverter valve is connected to the throttle body using an
o-ring inside the throttle body flange which is locked in place
by a c-clip, which works very well. It also make removal/installation quick and easy. The throttle
body lip is machined to accept this c-clip. It is not designed for
a silicone hose connection which is used by competing brand charge pipe upgrades on the market. The throttle body lip is too
short and there are no "beads" to prevent the silicone hose from blowing
off under boost. Even though it is the easiest way to "rig"
together, it is not ideal. The best way to connect the new
charge pipe to the throttle body is to replicate the same
connection. Therefore, ER CNC machined their own replica throttle body flange that utilizes the same
factory o-ring and c-clip for their Charge Pipe Upgrade.

NOTE: Meth Bungs are now an available
option on the Evolution Racewerks Charge Pipe.

What are Meth Bungs?
A Meth Bung Hole are predrilled and threaded holes designed for the use
of a meth kit.

The same
issue came with the MAP sensor. The MAP sensor seals to the
factory charge pipe via a o-ring on the sensor itself.
Having a hole in a silicone hose will definitely cause a boost leak as
it will not properly seal. Therefore, again ER CNC machined their own replica MAP
sensor flange that utilizes the same factory o-ring seal.

The Charge
Pipe Upgrade is available in the same 2 finish options as
Evolution Racewerks' intercoolers. It is available in a mirror polish finish. It is also available in
Evolution Racewerks'
Type III Hard Black Anodizing for the guys that want the
stealthy, factory look. An added benefit of the Type III Hard
Black Anodizing is that it hardens the aluminum piping and makes it more
durable against accidental damage (like dropping the pipe).

ER also
offers their upgraded Charge Pipe in any anodizing color of the
rainbow you want (special order) and is available in only Type II
Anodizing (aesthetics). It is available as a special order item and is
not stock.

Brush (or
plain) finish is also available.

The standard
option for Evolution Racewerks' Upgraded Charge Pipe is designed for either the
factory diverter valves or aftermarket "factory style" diverter valve.
Also available is the Tial Blow Off Valve option which utilizes the Tial
Q Blow Off Valve (BOV). The Tial Q BOV features a large 50mm (2") valve to quickly discharged built up boost pressure.
Since the Tial Q BOV vents to the atmosphere which causes
no restriction to venting boost, it
reacts faster than recirculated diverter valves. The internal valve
spring can be changed out to different spring rates which allow
adjustability. This allows versatility as it allows you to
increase the spring pressure in the future for
when you run higher boost levels. Therefore, it eliminates
the need to purchase another BOV or diverter valve if you increase boost
levels. The Tial Q BOV is available in 5 different colors: black,
polished, red, blue and purple. The black color option is
standard. If you want any other color, please specify when ordering.

ER can also
build their Upgraded Chargepipe to utilize any BOV or diverter
valve you desire. Love the way the HKS BOV sounds? No problem,
ER can
weld the HKS BOV flange on their upgrade Charge Pipe or any other
flange type so that you can utilize any BOV or diverter valve you want.
Due to the fact that there are so many options for BOV's and diverter
valves, it will be impossible for us to stock these options. Therefore,
it is available only as a special order and will be built to order.
